Options

A. On the day of ovulation
B. During first five days of menstrual cycle
C. During follicular phase of menstrual cycle
D. Once a week for first 4 months

Answer

**Step-by-Step Solution:**

1. **Understanding Steroidal Oral Contraceptive Pills**:
- Steroidal oral contraceptive pills are medications taken by females to prevent pregnancy. They contain hormones such as estrogen and progesterone.

2. **Timing of Consumption**:
- The effectiveness of these pills is closely related to the timing of their consumption in relation to the menstrual cycle.

3. **Evaluating the Options**:
- **Option 1: On the day of ovulation**: Taking the pill during ovulation may not be effective in preventing pregnancy since ovulation is the time when an egg is released and can be fertilized.
- **Option 2: During the first 5 days of the menstrual cycle**: This is when the hormonal levels can be controlled effectively to prevent ovulation and thus avoid pregnancy. This is the correct option.
- **Option 3: During the follicular phase of the menstrual cycle**: While it is possible to take the pills during this phase, their effectiveness is lower as the body is preparing for ovulation.
- **Option 4: Once in a week for 4 months**: This option is ineffective as the pills need to be taken daily to maintain hormonal levels that prevent pregnancy.

4. **Conclusion**:
- The most effective time to consume steroidal oral contraceptive pills is during the first 5 days of the menstrual cycle, which corresponds to Option 2.

**Final Answer**: The correct option is **Option 2: During the first 5 days of the menstrual cycle**.
